Abstract
The utility model provides an automatic intake and exhaust device applicable to the water storage type closed electric water heater. An elbow three-way side mouth with a return pipe is disposed with an automatic exhaust valve, the elbow three-way is connected with the water outlet of the water heater and the hot water inlet of a water mixer, the direct three-way of the side mouth connected with a valve is connected with the water inlet of the water heater and the safety valve, the cold water inlet of the water mixer is connected with the safety valve, the valve of the direct three-way is opened when tap water stops, the water in the automatic exhaust valve and the elbow three-way cavity enters into the water heater through the return pipe under the negative pressure, and the water in the water heater is discharged when the automatic exhaust valve is opened. When no water or little water exists in the water heater, air is exhausted from the automatic exhaust valve under the tap water pressure and water is automatically filled. The utility model is reasonably designed, is easily processed and used and has other characteristics, and thus has a very good value for promotion.
Description
Affiliated technical field
The utility model relates to a kind of air inlet and outlet device that is applicable to storage water heater sealing electric heater.
Background technology
The closed water heater generally adopts the principle of utilizing running water to extrude water at present, two drawbacks: the first, and must open mixed water valve when water heater adds water first, and will have the special messenger to look after.The second, when the running water stop supplies, there is water but can not put in the water heater, the user knows perfectly well has water but not use in the water heater.More than 2 deficiencies caused a lot of inconvenience to the user, also reduced the use value of water heater.
Summary of the invention
In order to overcome above 2 deficiencies, the utility model provides a kind of and has been applicable to that water storage is the automatic air intake and discharge device of sealing electric heater, when the running water stop supplies, can enter water heater by this device atmosphere, and the water of storing in the water heater can flow out; When running water just often, the gas in the water heater can be discharged by this device, device is closed during the water heater topped up with water, water heater recovers closed state.The technical solution of the utility model realizes in the following manner: be installed into exhaust apparatus on the outlet pipe of common closed water-storage electric heater; The jettison gear that matches with air inlet and outlet device is installed on the water inlet pipe of common closed water-storage electric heater.Air inlet and outlet device and jettison gear are reserved the interface of water-water jet and safety valve, do not influence normal mounting.After water heater installs, to connect running water and can add water, the gas in the water heater is discharged by the air bleeding valve on the air inlet and outlet device, and the full final vacuum valve of water cuts out water heater sealing work.When the running water stop supplies,, open the valve on the jettison gear if use the water of storing in the water heater, can return the water in air bleeding valve and the water heater outlet by the return pipe on the air inlet and outlet device into water heater, air bleeding valve is opened, and atmosphere enters water heater, the jettison gear water outlet.After water in the water heater used up, no matter when running water recovered supply, water heater all can be under the situation that nobody looks after topped up with water.Water heater has been realized cutting off the water and has been used and add water function automatically like this.Not only improved the use value of water heater but also made things convenient for the user to a great extent.
Description of drawings
Reach embodiment with reference to the accompanying drawings the utility model done following detailed description the in detail:
Accompanying drawing 1 is the novel structural representation of this use:
Accompanying drawing 2 is the novel connection diagram of sealing electric heater with storage water heater of this use:
The utility model by automatic exhaust steam valve (1), rubber blanket (2), elbow threeway (3), Return pipe (4), straight peen threeway (5), valve (6) form. Automatic exhaust steam valve (1) Elbow by gas thread and elbow threeway is plugged into, with rubber blanket (2) sealing, return pipe (4) Insert in the straight chamber of elbow threeway (3), end opening slightly is lower than the side mouth of elbow threeway (3), with Just cutting off the water can be whole with the water in elbow threeway (3) the side chamber with automatic exhaust steam valve (1) when using Demobilization, just intraluminal water can not take place causes automatic exhaust steam valve (1) when water heater adds water Close, row holds one's breath, and water heater can't add the phenomenon of water. Elbow threeway (3) is connected on water heater Delivery port on, with rubber blanket (2) sealing, water and air can only pass through return pipe (4) like this Communicate with the hot water mouth of automatic exhaust steam valve (1) and water-water jet. Straight peen threeway (5) is connected on hot water On the water inlet of device, valve (6) is connected on the side mouth of straight peen threeway (5), straight peen threeway (5) Lower termination safety valve, the hot water mouth of water-water jet and cold water outlet be connected on respectively elbow threeway (3) with On the interface of safety valve, other connection is identical with the connection of common water heater.
Embodiment
The utility model is reasonable in design, and is easy to make, and by specification accompanying drawing 1 processing and fabricating gets final product.Automatic exhaust steam valve, valve all are universal components.
Be illustrated below in conjunction with 2 pairs of concrete operations of the present utility model of accompanying drawing, running water is just often identical with the common water heater using method, when running water stops, if use the water of storing in the water heater, should open valve (6), the water in automatic exhaust steam valve (1) and elbow threeway (3) chamber promptly enters in the water heater by return pipe under the effect of negative pressure, and automatic exhaust steam valve (1) is opened, water heater becomes open type, can there are flowing out.As long as anhydrous or water discontented in the water heater, no matter when running water recovers normal, can both add water in water heater, fills it up with up to water, and automatic exhaust steam valve (1) cuts out, and water heater becomes till the sealing.
Automatic exhaust steam valve of the present utility model, valve all are general parts, have reasonable in design, be easy to processing, characteristics such as easy to use, just having realized cutting off the water under the condition that does not change the common water heater structure using to reach adds water function automatically, thereby has good value for applications.Except that the specification These characteristics, be the known technology of those skilled in the art.
Claims (4)
